If you’re looking to upgrade Office and get the latest version, you have different options depending on the version of Office you already have. See the sections below for what corresponds to your license of Office:

Office as a one-time purchase (non-subscription version)

One-time purchase versions such as Office Home & Student or Office Home & Business don’t receive an automatic upgrade. If you currently have a one-time purchase of Office you can buy an Office 365 subscription or the newest one-time purchase version.

Get an Office 365 subscription

Purchasing Office 365 is your best option. You'll always have the latest features, security updates, and other improvements. You also get 1TB of OneDrive storage as well as Office’s cloud connected features to help you maximize productivity across your devices, Skype minutes, and access to support. You can choose between Office 365 Personal (for one person) or Office 365 Home (for up to six people).

Get Office 2019

Get the newest non-subscription version of Office such as Office Home & Student 2019 or Office Home & Business 2019.

You can only install these versions of Office on one device. You'll get security updates and fixes during the supported period, but you won’t receive new features or any of the other Office 365 benefits.
